"If you just start training, don't force you to do 20 reps in one sitting, you can do it twice." Seeing that Xu Xuan was a little panting and trembling after doing eleven sit-ups, Zhang Chen said.

You can't be in a hurry in everything, plus Xu Xuan's foundation is not good, well, soft and weak, Zhang Chen can already feel it, eleven push-ups show the limit, her physical fitness is not good, and Zhang Yuxi is obviously incomparable.

"Okay." Xu Xuan breathed a sigh of relief, lay on the mat, and opened her mouth to breathe like an orchid.

Seeing Xu Xuan's chest rise and fall with a large amplitude, Zhang Chen said, "You can try abdominal breathing, which is good for the body." ”

"Abdominal breathing?" Xu Xuan's expression was a little dumbfounded, and she asked, "What is it?" ”

Zhang Chen explained to him.

Normal people like to use chest contraction and relaxation to drive the lungs to breathe, but the activity of the chest needs to drive more body structures, this way of breathing will bring a burden to the body, increase energy expenditure, and there are reports that this is a less healthy way of breathing, although most people adopt this breathing habit.

However, it is not necessary to have the chest involved when breathing, for example, abdominal breathing, which is a lighter way of breathing, that is, using the muscles of the abdomen to guide the lungs to relax and contract, this way of breathing avoids more muscle and bone involvement, and is considered a healthier way of breathing.

Zhang Chen explained to Xu Xuan.

Xu Xuan tried to follow the breathing method Zhang Chen said, and after a while, she mastered the method, "I understand." ”

After resting for a while, and finishing the remaining nine sit-ups, Xu Xuan was already sweating.

Zhang Chen handed her a towel, Xu Xuan took it, and slowly wiped the beads of sweat from her forehead.

The lady is really different, Zhang Chen feels that compared with Zhang Yuxi, Xu Xuan is more like a woman.

Zhang Yuxi...... Some of them are grinning.

"I have a copy of the Yijin Sutra here, you can take it gradually, I think this is suitable for you." Zhang Chen took out a copy of the Yijin Sutra out of nowhere and handed it to Xu Xuan.

"What, Yi Jin Jing?" Xu Xuan was a little surprised, "I can't do it......"

"Heh, it's just that the name looks tall, the full name is "Yijin Jing Gymnastics Exercise", you can just treat it as gymnastics."

"Oh, I'll take a look." The surprise on Xu Xuan's face quickly disappeared, and she took the "Yijin Jing" in Zhang Chen's hand.

looked through it and found that it was indeed what Zhang Chen said, a set of gymnastics. and the kind of martial arts cheats in the novel, which has nothing to do with at all.

The main content of the Yijin Sutra is based on the bones and muscles of the human body, which lists in detail the bones and muscles that the human body can move and exercise, and details it to each part. Exercising these musculoskeletal and tendon sheaths helps to promote good health.

After a while, according to the instructions in the book, Zhang Chen assisted Xu Xuan in pulling her hamstrings, and her movements were a little ambiguous.

"How are you two here?" Zhang Yuxi only felt that he was frequently sprinkled with dog food.

……

Night falls.

"Brother, let's go out to kill zombies, that sister-in-law is home alone, won't there be a problem?" Zhang Yuxi asked Zhang Chen.

"You also know that she is your sister-in-law, why do I think you are full of jealousy?"

"It's different, there's a dark shadow hiding in the house, and after we leave, are you sure it won't eat people? If you eat your Xu Xuan, you can cry. Zhang Yuxi kindly reminded.

Zhang Chen understood that Zhang Yuxi seemed to be jealous, but this did not mean that she had hatred for Xu Xuan.

"Take her with you, and let Xu Xuan see what it's like to hunt zombies in the apocalypse." Zhang Chen also took into account the problem of the black shadow.

The black shadow seemed to be hiding at the moment and would not appear again in front of them, and it was also before, after Zhang Chen and Zhang Yuxi's blood and magic aura broke through for the third time, it seemed that it was because of the strength of their aura that the black shadow was threatened, so that it was scared to hide all the time?

But no matter what, the black shadow is afraid of them, but he is not afraid of Xu Xuan, Xu Xuan is just an ordinary person.

on an F1 car.

Zhang Chen's car is the kind of model that has a co-pilot.

Zhang Yuxi and Xu Xuan squeezed, and the passenger seat barely accommodated the two of them.

The cars went in and out, and this time the target was still the city center.

In the huge city center, they have only cleaned up the zombies in some areas in the past few days, and they have not been able to empty the zombies in the entire urban area.

Zombies are a relatively easy threat to deal with, but if they are other weird, sometimes you have to take a detour.

But they have the ability to protect themselves, and there are a few times when they easily retreat.

Hangzhou city center.

A certain building.

Zhang Chen unleashed a bloody blade at the second-floor window, tearing apart the zombies wandering on the ground.

Not far away, blood bats tore at the corpses, attracting many zombies.

Soon, a large group of zombies rushed forward one after another, rushing in the direction of the building.

Xu Xuan looked at this scene, breathing rapidly, clenching her fists very nervously.

He glanced at Zhang Chen, and then his gaze was on Zhang Yuxi's face, and he didn't see the slightest nervousness in their expressions.

"What Zhang Chen and his sister have experienced, in the face of the tide of corpses, they can't see the slightest fear."

At this moment, Xu Xuan has a lot of thoughts in her mind, facing the corpse tide for the first time, it is normal for a weak woman to have instinctive fear.

"Although the first floor has been protected, the zombies outside can't enter, but what if there are flying zombies?"

Xu Xuan has read some apocalyptic novels, in the apocalypse, zombies continue to evolve, from the beginning of being able to walk on two legs on the ground, to the end of the evolution into creepers, who can climb on top, and then to the back, evolving more terrifying flying abilities......

Xu Xuan gasped, she saw that the tide of corpses below had hit the door on the first floor, although it was defended, but who knows how many times it could resist?

"Why do they still look like they're calm and breezy?" Xu Xuan felt a burden in her heart, and she couldn't breathe.

Obviously, the zombies are approaching, and there is a tendency to break through the door and enter the building, but the faces of the two are still calm and calm.

This made her feel some strangeness to Zhang Chen.

The Zhang Chen in front of her was a little different from the Zhang Chen she knew in the past.

Zhang Chen's hand rested on Xu Xuan's shoulder, "Don't be afraid, I will take a look at these zombies below, and you will gradually find that they are actually quite cute." ”

"Huh?" Xu Xuan opened her mouth.

"yes, it's cute, these zombies." Zhang Yuxi also followed Zhang Chen's words and said, "Because they are rookies." ”

After that, Zhang Yuxi condensed the ice pick in his hand and bombarded it!

Those zombies that hit the door on the first floor were frozen in an instant, unable to move.

After her magical aura metamorphosed for the third time, it increased by eight times, and again

In addition, he has a 100% ox power burst talent, and he has double the damage continuously, and any ice pick is a large-scale attack.

Xu Xuan had an unconcealable shock on her face.

She originally thought that only Zhang Chen was an alien, but now she found out that among the three people, she was the only ordinary person.

Suddenly there was a lot of pressure.
